What are different types of optical cables?

Usually, three types of optical cables with optical fiber are used: disposable, more mode and plastic optical fiber (POF). The type of cable used depends on its use. MULTI-MEZIM and one mode are used in networks with optical fibers to transfer data. Pof cables are generally not used to transfer data, but instead are used for aesthetic purposes, such as toys and decorative displays.

Optical cables, regardless of their use, are created in a similar way. Two layers of glass or plastic are melted together to form a core and cladding; Returning is an outer layer. This structure is then expanded to form a long, very thin fiber. The fibers are then cooled and inserted into the coils. They are connected together to create cables with optical fibers with another coating called jackets, around them for protection.

different types of optical cables differ in consistency and size, but most of them are thinner than human hair. In the case of cables with moreThe modes A with one mode, the glass used to produce them is very clean, as the refractive properties must be highly standard in order to make a data signal - in this case made from light - through the network. Plastic cables are not made of such high quality material, so it is much cheaper to buy and produce; They also have a stronger diameter.

disposable fiber cables have a thin core; They only enable one data mode, unlike multi-rim, which can use several different modes. Cables with one mode provide higher transfer speed and can carry a signal 50 times further than multi-rosim, but are also more expensive. In the narrower core core with one mode and its use of a single light wool, it provides the smallest signal attenuation and the highest speeds between different types of optical cables available. Its biggest disadvantage is that it needs a light source with a narrow spectral rangeEM, and can only use one way of transmission.

Multi-Mode Fiber-Optic cables have a stronger core than one mode. May bear data that has been coded using multiple light sources sources; This allows you to send multiple signals to one cable. Multi -modes fibers provide high bandwidth at high speeds at short to medium distances. The disadvantage of the cable with multiple modes is that due to multiple data streams, the signal is distracted to longer distances, leading to incomplete and inaccurate data transfer.

plastic optical fibers usually do not clean the signals needed for larger optical networks, but can be used in small networks with a transmission distance less than 100 feet. Since the end of the 90s. However, they are more often used in toys or decorative displays that produce light signals. An example of this is the electronic reproduction of the flower vases, anywhere they are replaced by optical fibers. Pof is the cheapest to formbetween different types of optical cables.
